<p class="level0">CURLOPT_CLOSESOCKETFUNCTION - callback to socket close replacement function <a name="SYNOPSIS"></a><h2 class="nroffsh">SYNOPSIS</h2>
<p class="level0">#include &lt;curl/curl.h&gt; 
<p class="level0">int closesocket_callback(void *clientp, curl_socket_t item); 
<p class="level0">CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CLOSESOCKETFUNCTION, closesocket_callback); <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">Pass a pointer to your callback function, which should match the prototype shown above. 
<p class="level0">This callback function gets called by libcurl instead of the <span Class="emphasis">close(3)</span> or <span Class="emphasis">closesocket(3)</span> call when sockets are closed (not for any other file descriptors). This is pretty much the reverse to the <a Class="emphasis" href="./CURLOPT_OPENSOCKETFUNCTION.html">CURLOPT_OPENSOCKETFUNCTION</a> option. Return 0 to signal success and 1 if there was an error. 
<p class="level0">The <span Class="emphasis">clientp</span> pointer is set with <a Class="emphasis" href="./CURLOPT_CLOSESOCKETDATA.html">CURLOPT_CLOSESOCKETDATA</a>. <span Class="emphasis">item</span> is the socket libcurl wants to be closed. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
<p class="level0">By default libcurl uses the standard socket close function. <a name="PROTOCOLS"></a><h2 class="nroffsh">PROTOCOLS</h2>
